Title: Improvements in and relating to cutting off mechanism in cigarette making and similar machines, wherein the rod or the like is moving continuously in a lengthwise direction
IPC: A24C5/28
Filed: 1925-07-31
Abstract: 261,821. Cole, W. July 31, 1925. Cigarette-making machines. - In a cutting mechanism for continuous-rod machines, a dished, conical, or cylindrical cutter is revolved bodily about an axis, other than the axis of formation, with uniform velocity and is located so that the centre of curvature traces the base circle of an involute about the axis of bodily revolution. The cigarette rod is moved continuously axially across the path of the cutter, and the axis of the rod is inclined to the plane of the base circle so that the cutter intersects the rod once per revolution. A dished cutter a, Fig. 1, is secured to an arm b with axis ZZ, held to a rotating shaft d, and the centre of curvature 0 of the cutter traces a base circle f about the axis XX. The axis ZZ lies in a plane parallel to the axis XX, which is tangential to the base circle f. The cutter a cuts the plane WW of the circle f and the rod g is slightly inclined to the plane of the circle f. The axis YY of the rod g is so positioned that during the cutting the point 0 coincides with the axis XX. The length of rod cut off is equal to the circumference of the base circle. In Fig. 6 the cutter is rotated about ZZ by a gear 24, and about XX by gearing 22. The length of rod cut is varied by adjusting a crank 27.

A hinge comprises a pair of hollow cylindrical sheaths 1 (Fig. 1) longitudinally slotted at 2, one of which has welded therein a pin on which the other can pivot, and a pair of brackets for fixing the sheaths to the members to be hinged together, each bracket comprising two parallel plates 4 (Fig. 2), at least one of which has a flange 13, terminated by heads 5 slidably fitted into the respective sheath through the slot 2 and locked therein. The heads 5 are semi-cylindrical and separated by a slot 6 and are locked inside the sheath by screws or pins 14 (Fig. 7) inserted through holes 3 in the sheath to force the heads apart so that they grip the inside of the sheath. Alternatively the bracket is locked to the sheath by driving a pin axially between the heads. In a modification (Fig. 8) the plates 4, instead of being fixed to the hinged member by screws passing through holes 7, are each formed with a flange 13 and pass through a mounting plate 10 (Fig. 5) which is screwed to the member. Various alternative forms of sheaths and mounting plates are described (Figs. 10-14, not shown). A bronze washer is placed on the pivot pin between the two sheaths. The free ends of the sheaths are left open for lubrication purposes, and may be covered by removable caps.

Abstract: 638,832. Bread-slicing machines. ROSE BROS. (GAINSBOROUGH), Ltd. July 22, 1947, No. 19576. [Class 5 (i)] Means for adjusting the lateral spacing of a series of slicing knives in a machine having a series of knives arranged in parallel relationship comprises a series of guides 17, formed in supporting members 24, each member 24 having cam surfaces 31 on one side arranged to pass through slots in the side of an adjacent supporting member, and arranged to be slidably mounted on supports 26, 27. Each member 24 is provided with a spacing member 33 slidable longitudinally in a channel in said member and provided with cam surfaces 34 engaging the complementary cams 31 on the adjacent supporting member to form an abutment for that member. Each spacing member 33 is provided with a toothed rack which co-operates with a common gear 38, the rotation of which by wheel 47 varies the lateral spacing between cam surfaces 31 and 34 of adjacent supporting and spacing members and thus determines the extent of the lateral movement of the supporting members 24 towards each other. Each supporting member has a pin 43 with a head 44 which engages a recess in the adjacent member 24 to form a stop which limits the lateral movement of each supporting member away from its adjacent member, which movement is imparted by a screwed bearing 42 connected to the outer member 24 and rotated by a screwed bush 62 connected to a wheel 63. The handle 47 is spring-urged so that notches 49 thereon co-operate with notches 51 on a frame member 52 to lock the gear 38 in any required position. A pointer 56 indicates the setting of guides 17. In use the members 24 are separated as far as possible by rotation of wheel 63 and the position of the spacing members is adjusted by wheel 47, wheel 63 is then rotated in the reverse direction to close the members 24 until cams 31, 34 abut against each other. It is stated in the Provisional Specification that a central supporting member is held stationary and two end supporting members are attached to screw devices arranged to extend or collapse the supporting members in succession from both ends.

Title: Improvements in and relating to processes for treating coal
Inventor: LITTLECHILD JAMES EDGAR
IPC: C10L9/06
Filed: 1951-08-23
Abstract: 719,225. Treating coal. NATIONAL COAL BOARD. Aug. 25, 1952 [Aug. 23, 1951], No. 19885/51. Class 50 A process for treating coal to reduce its agglutinating value comprises treating the coal in pulverulent form as a fluidized mass with a gas containing free oxygen at a temperature above that at which carbonization would normally occur, the operating conditions being such that the coal does not undergo substantial carbonization. The coal is preferably preheated to a temperature of at least 80‹ C. and the moisture content reduced to not more than 0.5 per cent by weight before the oxidizing treatment. In an example a coal having a substantial combustion temperature of 420‹ C. was treated at 450‹ C. and the agglutinating value of the coal was reduced to zero. In apparatus described for carrying out the process fine coal is fed by a worm feed 8 from a hopper 4 into a fluidized treatment zone 6 having an upper portion of increased diameter. Air supplied at the base of the zone 6 by a blower 9 preferably after having passed through a preheater 10. The air passes out of the zone 6 through a cyclone separator 12, separated fines being returned to the mass in the treatment zone by a pipe 11. From the separator 12 the air passes through a second separator 13 and finally out through line 14 whence it may be used for preheating the coal in a preheating chamber 2. freated coal is withdrawn through line 15 passing through a cooler 16. Cold air for cooling the coal enters the cooler 16 through line 22 and leaves by line 19 and is used in preheating chamber 2. Fines from the separator 13 are discharged into the cooler 16.

Title: Improvements in or relating to Rope, Strand or the Like
Inventor: CAMPBELL ROBERT EDWARD
IPC: H01B7/30
Filed: 1965-12-09
Abstract: 1,182,593. Making ropes and strands. BRITISH ROPES Ltd. 9 March, 1967 [9 Dec., 1965; 5 May, 1966], Nos. 52223/65 and 19929/66. Heading D1T. A strand is formed by drawing wires and filamentary components of elastomer through a sizing or compacting means under conditions of temperature and tension, that will cause the filamentary components of elastomer to fill by plastic flow the interstices between the wires. The elastomer flow may also be used to provide a sheath around the strand or an elastomeric' sheath may be applied subsequently. The filamentary components of elastomer may have a wire running therethrough. Filaments that are initially of half lock section may also be used. In Fig. 2 the wire and elastomer filaments converge through bores in a nose piece 7, this nose piece being surrounded by means (not shown) supplying hot air. The heated wires and elastomers then pass through a rotary forming die 13 in a housing 9 slidable along parallel bars 28. The die 13 has electric heating means 14 and is thermostatically controlled at a specified temperature indicated by a thermocouple 14a. The nose piece 7 has fingers 7C that engage the die 13 such that the nose piece 7 and the die 13 rotate in synchronism. A spring 8 presses the nose piece 7 against the die. To ensure that the voids betweeen the wires are completely filled with elastomeric material, the resulting strand is passed through a heated stationary annular die 15, also adjustable along the bars 28. The bore of the die 15 is some 8% to 30% less than that of the die 13 and is maintained some 65 to 100 degrees centigrade higher than the die 13. The dies 13 and 15 can be combined into a single die, such a die Fig. 38 (not shown) possessing a large bell entry mouth, followed by a progressive reduction in diameter to the requisite bore, in turn followed by a parallel land, the length of which is at least ten times that of the die bore at its minimum diameter. A coating die 20 may be added to apply a sheath of elastomer. The resulting strand passes through a cooling spray containing an anti-adhesion agent circulated from a tank 25 to a nozzle 24.
